Dungs VPS504 S04 Flame Detector
Technical specs, application notes, replacement checks, and related model references.
Product Overview
The DUNGS VPS504 S04 is an advanced Valve Proving System (VPS) designed to verify the integrity of safety shut-off valves prior to burner ignition or after shutdown. By precisely monitoring the pressure dynamics between two solenoid valves, it detects micro-leaks that could lead to catastrophic fuel accumulation in the combustion chamber. Operating independently of system pressure variations, it provides a definitive fail-safe diagnostic, fulfilling the stringent requirements of EN 1643 for large-capacity industrial burners.

Selection Notes & Data Verification
The VPS504 S04 page is structured for engineering comparison: confirm the product type, firing range, fuel type, operating mode, electrical supply, and safety approvals against the manufacturer datasheet before specifying the burner or component.
Burner.wiki normalizes product data for discovery and comparison, but final selection should account for combustion chamber backpressure, local emission limits, control sequence requirements, and site commissioning conditions.
